Our d3 team is not sponsored by any big companies so we are free to use basically any gear we want and for 2013 I have already picked up a slightly used dm12 for 2013. I have a z2 from last season so I am wondering if I should look into the rotor for 2013 or stick with the z2. The z2 was amazing dont get me wrong but the rotor's build quality in terms of durability is awesome in my eyes. The only thing im not fond of is its tendencies to jam and me playing in southern California, I could see that being a problem.
Basically rotor with its superior build quality and looks/same maker with the dm but it jams more often or z2 with higher capacity and bigger feed port and much fewer jams.. Just wanting to see what others have to say.

I absolutely hate the spires looks. im thinking rotor with with soft arm?

NO! Don't get the soft arm, it has caused constant jams in the Rotor of every person that had one. You can lower the tension setting on the Rotor if you are concerned with jams. I have never had a jam with my Rotor - not once! - but I would say stick with the Z2 unless you get a trade deal on a Rotor you know works well, there isn't really much performance difference between them IMO.

My friend has both for tournament play. He uses the z2 and only pulls out the rotor if he has a ball break in his z2. His experience is that the z2 feeds more consistently even if the paint isn't the best. With tournament grade paint, the rotor should be fine, but if you use lower quality paint during practice, the z2 would probably be a slightly better option. A more expensive option if you prefer the rotor is the seed kit, but finding one now is probably going to be difficult.

If you want to get sponsored, present yourself as a mature adult, not a four year old with a crayon.

It's a matter of what you look for in a hopper. I've used both of them and like what each have to offer. Both of them will work perfectly fine on the field.

The Rotor:- Super simple, idiot proof design. (Less maintenance. You can take it apart in less than 30 seconds.)- Durable as hell. (Both are very very durable but the Rotor takes a slight edge just because you don't really need to worry about a fried board.)- Add a Speedfeed + lid attachment. This makes it the ideal choice for rainy days.- Much more efficient on batteries.- Customizable colors

The Z2:- Sound-activated, more reliable feeding. (You'll notice less jams.)- Automatic anti-jam (If it detects a jam it will un-jam itself for you.)- Customizable settings (You can adjust the speed and sound of how it feeds.)- Rip drive (You can manually un-jam/feed your paint in case it runs out of battery or something goes wrong. Also, the rip drive is much better at un-jamming paint than the Rotor's fin switch... If your Rotor breaks down or runs out of battery you'll have a hard time feeding it manually.)- Easier and faster to switch lids back and forth.

I love my rotor and have never had any problems with it. The only time it has ever jammed on me was when I was using really terrible paint and when I was playing woods and a small stick fell in the speed feed. If you're going to be playing tournaments then paint shouldn't be an issue, and as far as manual feeding with a dead battery goes you should always have fresh batteries in all your gear when you start a tournament. So, I would choose rotor, but that's just me.

EDIT: Also, I play in south Alabama so I know a thing or two about playing in high heat and humidity, and I still don't have any problems with my rotor.
